' V LENTIN BIELA', or .oust.onowa axis.

To all whom it may concern:

Be it known that I, VALENTINE 'BIELA,

a citizen of the United States, residing at Cestohowa, in the county of Karnes and State of Texas, have invented new and useful Improvements in Gear-Wheels, of which the following is a specification.

This invention relates to gear wheels, and

its primary object is to provide a construcv tion of wheel and gear rim, whereby an ordinary buggy, wagon or other vehicle v construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawing'in which Figure 1 is a side elevation of a portion of a gear. wheel constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a transverse section on the line 33 of Fig.- 1. Fig. 4 is a section taken circumferentially of the wheel through the joint.

Referring to the drawing 1 designates the rim or felly of a wheel of any ordinary construction, such as a vehicle wheel of the character set forth, from which theusual tire has been removed. Surrounding the said felly 1 is a gear rim 2 provided'with the usual gear teeth 3. This gear rim'2 may consist of a split ring 'made in a single H piece, or it may be made of a series of gear segments.

I I have not deemed it necessary in the present instance to illustrate a gear rim of sectional construction, as the same principle of uniting the ends of a rim made of a single piece'or the adjoining ends of a series of segmental rim sections will be employed and is herein fully disclosed.

As shown the'ends 4: and 50f the gear rim are provided upon their inner surfaces with transversely extending plates or coupling members 6 and 7, which are secured thereto by rivets 8 passing through the body of the.

rim and the adjacent gear teeth. These plates extend beyond the sides of the felly .1 and rim 2 and are provided'with terminal loops or eyes 9, theloops or eyes 9 at each" side of the wheel being connected by a fastening belt 10 provided with' an adjusting and retaining nut 11. j

It will be understood from, the foregoing that when rim 2 is applied to, the felly 1 and thenuts 11 are tightened up the rim 2 may be drawn as securely as desired about the felly, by which it will be contracted to.

the desired degree'to hold it from displace ment@ The wheel lfthus equipped witha gear rim 2 of the construction described is adapted to efficiently perform the functions countersunk in sockets or mortises 12 in the.

face of the felly 1, by which-the gear rim is 'held from slipping around the felly under the pull of the traction chain. 7

It willbe observed that byfastening the plates to the rim by means of rivets which pass through the adjacent gear teeth, a strong and durable coupling connection is secured without weakening the gear rim'inanv particular.

I vclaim,: j 7 1. The combination. in a gear wheel, of a ,wheel proper having .a felly' provided with in line with said'mortise, coupling plates fixed to the ends of the gearrim and seated said felly and having endportions disposed in said mortise and proiecting beyondthe sides of the run, said plates being provided with terminal eyes, and coupling bolts passwalls in the mortise to hold the rim from v. gcreeping uponthe felly.

I 2.- The combination, in a v 7 gear wheel, of a wheel proper having a felly provided with a recess or mortise'in the peripherv thereof,

a split gear rim surrounding said felly and having end portions disposed in line with said mortisegcouplingplates extending body portion and adjacent teeth of the Wheel transversely on the inner side of the ends of the Wheel and uniting the ends of the of the rim and projecting beyond the sides gear rim. of the rim and provided With terminal eyes, 1 In testimony whereof I ailix my signature rivets passing through said plates and the in presence of two Witnesses.

rim and fastening said plates to the Wheel Witnesses: rim, and coupling bolts passing through the JOHN KYRISH, eyes of the coupling plates at opposite sides i BRoN KYRISH.
